UNITED STATES MARK GOODWIN, OF NEW YORK, N.

Y., ASSIGNOR OF ONE HALF OF HIS RIGHT TO WILLIAM D. TRACY, OF SAME PLAGE.

FLOATING DUMPlNG-PLATFORM.

SPECIFICATION forming' part of Letters Patent No. 228,058, dated May 25, 1880.

Application filed June 23, 1879.

To all whom t may concern:

Be it known that I, MARK GOODWIN, of the city, county, and State of New York, have invented a new and useful Improvement in Floating Dumping-Platforms, of which the following is a specification.

Figure l is a side View of my improved platform. Fig. 2 is a top view of the same.

Similar letters of reference indicate corresponding' parts.

The object of this invention is to furnish an improved dumping-platform which shall be so constructed that it may be readily taken from one pier to another, as may be required, and which shall be simplein construction and convenient in use.

The invention consists in a scow or float provided With a frame, and a platform having its forward side projecting, and provided with the stop-tiinber,the guard -railin gs, and one or more hinged bridges to adapt it to be placed at the side of a pier for use in dumping the loads of carts into a receiving-vessel, as hereinafter fully described.'

A represents a scow or other floating structure, upon which is built and to which is attached a frame, B. To the frame B is secured the platform C, which is provided with guard-railings c at its sides, a stop-timber, c2, at its front for the cart-wheels to back against When `dumpin g the loads, and a guardrailing, c3, at its rear side, between the gangways. To the platform C, at its gangways, near the ends of its rear side, are hinged the inner ends of the bridges D, the outer ends of which rest upon the pier. The bridges D are hinged to the platform O by round cross-pieces -dumping-pier without its being' necessary to permanently erect any structure upon the said pier, and leaving it wholly uninjured when the dumpin g-platform is removed to another place. In using the platform the scow or float A is secured to the pier, and the bridges D are arranged upon it. The carts to be unloaded are driven over one of the bridges D to the plat form'U, are turned around and backed up against the stop-timber c2, their loads are dumped into the receivingvessel, and they are driven oil' over one of the bridges D.

One or more bridges D may be used, as may be desired or convenient, or as the amount of dumping to be done may require.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- A lio-at provided with frameB and platform C c c2 c3, in combination with the hinged bridges D, adapted to be extended to piers, as shown and described.
